Subject: Proposal: Inclusion of user defined gradients using graphics/SVG in the Office specification
Title: Message
|
I propose keeping the existing gradient specification in it's current form.
In order to allow others to extend this specification, we should add an
attribute to allow users to create their own 'gradient' types. By allowing a
vector format such as SVG to describe this gradient type, we can handle cases
that we cannot previously predict. The changes to the format are:
- Add userdefinedgradient to the list of
gradient-style that can be supported.
- <!ENTITY % gradient-style
"(linear|axial|radial|ellipsoid|square|rectangular|userdefinedgradient)">
- Add draw:userdefinedgradient to the attribute list of
draw:transparency and draw:gradient.
- This would be an XLINK to
access the graphic stored within
the overall file that would
define the gradient. The size would be defined by the view within the
graphic. The top-left, bottom right
coordinate of the view of the graphic would be scaled to the size of
the item being affected by the gradient.
- Add
draw:userdefinedgradientitem to the an appropriate
section to hold the gradient rendering information. The XLINK/URL would
reference/index this item.
- Would contain the graphic and
gradient co-ordinate/transformation information.
- The mapping system will be defined inside
of the gradient descriptor, such as to use
Red component, RGB component, brightness component, or ALPHA component from
the graphic itself. This will be an attribute corresponding to the info to
use from the graphic.
- RGB, R, G,
B, ALPHA, H, S, B, C, M,Y, K are all color systems that should be able to be
used from the original graph.
